Quotes from David Quammen

Mathematics to me is like a language I don't speak though I admire its literature in translation.

This form of interspecies leap is common, not rare; about 60 percent of all human infectious diseases currently known either cross routinely or have recently crossed between other animals and us.

Sir Peter Medawar, an eminent British biologist who received a Nobel Prize the same year as Macfarlane Burnet, defined a virus as "a piece of bad news wrapped up in a protein.

disappointment, in science, is sometimes a gateway to insight.

When a pathogen leaps from some nonhuman animal into a person, and succeeds there in establishing itself as an infectious presence, sometimes causing illness or death, the result is a zoonosis.

Ecological disturbance causes diseases to emerge. Shake a tree, and things fall out. Nearly all zoonotic diseases result from infection by one of six kinds of pathogen: viruses, bacteria, fungi, protists (a group of

How do such diseases leap from nonhuman animals into people, and why do they seem to be leaping more frequently in recent years? To put the matter in its starkest form: Human-caused ecological pressures and disruptions are bringing animal pathogens ever more into contact with human populations, while human technology and behavior are spreading those pathogens ever more widely and quickly.

What do we measure when we measure time? The gloomy answer from Hawking, one of our most implacably cheerful scientists, is that we measure entropy. We measure changes and those changes are all for the worse. We measure increasing disorder. Life is hard, says science, and constancy is the greatest of miracles.

Some of these viruses," he warned, citing coronaviruses in particular, "should be considered as serious threats to human health. These are viruses with high evolvability and proven ability to cause epidemics in animal populations.

Ebola is a zoonosis. So is bubonic plague. So was the so-called Spanish influenza of 1918–1919, which had its ultimate source in a wild aquatic bird and, after passing through some combination of domesticated animals (a duck in southern China, a sow in Iowa?) emerged to kill as many as 50 million people before receding into obscurity.

Our findings highlight the critical need for health monitoring and identification of new, potentially zoonotic pathogens in wildlife populations, as a forecast measure for EIDs." That sounds reasonable: Let's keep an eye on wild creatures. As we besiege them, as we corner them, as we exterminate them and eat them, we're getting their diseases.

He hoped these students would learn how to be at home in the desert, not how to conquer it; and he hoped that, in the process, they might discover the spiritual value of quietude.

One further factor, possibly the most crucial, was inherent to the way SARS-CoV affects the human body: Symptoms tend to appear in a person before, rather than after, that person becomes highly infectious. The headache, the fever, and the chills—maybe even the cough—precede the major discharge of virus toward other people.

The next day, William Lanney's much abused remains were carried in a coffin to the cemetery. The crowd of mourners was large. It included many of Lanney's shipmates, suggesting that the whaling profession in late-nineteenth-century Hobart was graced with a higher level of humanistic sensibility than the surgical profession.

I'm a white, middle-class male who had a happy childhood in Ohio. The world does not need me to be a novelist.

I was a prodigy who learned how difficult writing was only after getting published. I paid my dues later.

Ebola isn't a respiratory virus. It doesn't spread through the airborne route. So it's not likely to spread like wildfire around the world and kill tens of thousands or hundreds of thousands of people. That's what I think of as the next big one.

If you are lying in a tent in the Congo jungle, you don't want to be reading about rainforest biology. You want to be in a distant world.

I thought 'The Hot Zone' was fascinating, mesmerizing. It's one of the things that got me interested in Ebola.

On April 3, 2014, Jane Goodall turned 80. The iconic blond ponytail has gone gray, but the sparkle of intelligence, sly humor, and fierce dedication still shines from her hazel eyes.

There's a belief in some cultures that if a person experiences good fortune in financial terms and does not share the good fortune, when that person becomes ill with a mysterious fever and dies, people tend to say: 'Aha! It was because he didn't share. It was the spirits who brought him down.'

Most Americans know nothing about the African forest, and it seems to them a very scary, spooky dangerous place. I've spent a lot of time in the forests of central Africa. I know they're beautiful places that contain a lot of different kinds of creatures, including some that carry Ebola.

Identity is such a crucial affair that one shouldn't rush into it.

The more cases of Ebola infection we have, the more chances there are for the virus to mutate in a particular way that adapts it well to living in humans, replicating in humans, and perhaps transmitting from human to human.
